Psychopathy scores and violence among juvenile offenders: a multi-measure study,

BEHAVIORAL SCIENCES & THE LAW, Issue 1 2004
Daniel C. Murrie Ph.D.
This study examined the relations between psychopathy scores and violent behavior in 113 incarcerated adolescents. We compared the results of four different instruments designed to assess psychopathy features among juveniles,the Psychopathy Checklist: Youth Version (PCL:YV), two versions of the Antisocial Processes Screening Device (APSD), and a Psychopathy Content scale on the Millon Adolescent Clinical Inventory (MACI). We found that PCLY:YV scores were significantly correlated with violent offense history, unadjudicated violence, and institutional violence, as well as measures of the severity and instrumentality of prior violence. Receiver operating characteristic analyses generated statistically significant effect sizes (AUC values) ranging from 0.64 to 0.79. The three other measures generated statistically significant correlations with one or more of the violence criteria, although correlations and effect sizes tended to be smaller in magnitude. Our results offer some support for the validity of these measures of psychopathic features, and the value of the PCL:YV in particular, with respect to short-term measures of violence outcome among juvenile offenders.

Facets on the psychopathy checklist screening version and instrumental violence in forensic psychiatric patients

CRIMINAL BEHAVIOUR AND MENTAL HEALTH, Issue 4 2010

Background,There is a recognised relationship between psychopathy and instrumental violence, but not all violence by people who meet the criteria for psychopathy is instrumental. Aims,Our aims were to compare offence types among forensic psychiatric patients with and without the Psychopathy Checklist: Screening Version (PCL: SV) criteria for psychopathy. Our specific questions were whether factor 1 , the interpersonal affective dimension , was related to instrumentality and on severity of the violent crime. Our hypothesis was that the relationship between psychopathy and instrumental violence would be dependent on the severity of the violent crime. Methods,Sixty-five male patients at the forensic psychiatric hospital in Sundsvall, all with a violent criminal history, were assessed for psychopathy through interview and records using the PCL: SV. Severity and the instrumentality of their previous violence were coded using the Cornell coding guide for violent incidents. Results,The interpersonal features of psychopathy (the interpersonal facet), and only the interpersonal features were significantly associated with instrumentality and severity of violence. Instrumentality was also significantly related to the severity of the violence, independent of psychopathy score. Conclusions,The results indicated that, at least among forensic psychiatric patients, planning is more likely than not with respect to serious crimes. The specific link between interpersonal features of psychopathy and instrumental and severe violence suggests potential clinical value in recognising subtypes of psychopathy.

Comparing Two Alternative Measures of General Personality in the Assessment of Psychopathy: A Test of the NEO PI-R and the MPQ

JOURNAL OF PERSONALITY, Issue 4 2009
Eric T. Gaughan
ABSTRACT This study examined the interrelations between two measures of personality, the Revised NEO Personality Inventory (NEO PI-R; P. T. Costa & R. R. McCrae, 1992) and the Multidimensional Personality Questionnaire (MPQ; Tellegen & Waller, 2008), and their relations with psychopathy in a sample of undergraduates. Results revealed good convergence between conceptually related personality traits; however, the NEO PI-R facets accounted for more variance in the MPQ subscales (mean R2=.49) than did MPQ subscales in NEO PI-R facets (mean R2=.35). Both accounted for substantial proportions of variance in psychopathy scores, although the NEO PI-R accounted for larger proportions and manifested greater incremental validity when using the broader domains of each measure; the differences decreased when the narrower facets/subscales were used. The results suggest that, although both measures assess psychopathy-related traits, the NEO PI-R provides a more complete description because of its assessment of interpersonal antagonism and the central role of this construct in psychopathy.

The relationship between attention deficit hyperactivity disorder, conduct disorder, and psychopathy in adolescent male and female detainees

BEHAVIORAL SCIENCES & THE LAW, Issue 4 2009
Kathrin Sevecke M.D.
Although ADHD and CD are apparent risk factors for adult psychopathy, there are three distinct perspectives regarding their relationships to psychopathy: (1) ADHD may contribute uniquely to the development of psychopathy or (2) its contribution may reflect its high comorbidity with CD. Alternatively, (3) the comorbid presence of ADHD and CD may confer unique risk for the development of psychopathy. Although prior adult studies have yielded conflicting findings, no prior studies of adolescents address this issue. We examined these three hypotheses and the possibility of sex differences using cross-sectional analyses in 90 male and 123 female incarcerated adolescents. Among males the influence of ADHD was largely attributable to the overlap between ADHD and CD, whereas among females ADHD contributed independently to psychopathy scores and to scores on several dimensions of psychopathy. In addition, among females, the ADHD,×,CD interaction was significant for the total score and the antisocial component of psychopathy and in a direction opposite to that predicted by the comorbid subtype hypothesis. These findings indicate that there may be sex-specific pathways to elevations in psychopathic traits and suggest that the comorbid subtype hypothesis is probably not correct for either boys or girls.
